Used primarily in organic synthesis as a building block for pharmaceuticals, it plays a key role in the development of drugs targeting neurological disorders. Its structure is valuable in creating compounds that interact with neurotransmitter systems, aiding in the treatment of conditions like depression and anxiety. Its hydrochloride form improves solubility, making it more effective in aqueous reactions and formulations. It is also utilized in scientific research to study neurotransmitter mechanisms and develop more effective therapeutics.
